摘要

Abstract The influence of the temperature of hydrothermal carbonization and torrefaction on the properties of biochar obtained from biomasses (peat and sawdust) and model mixtures of structural components (cellulose, hemicellulose, and lignin) prepared in percentage ratios corresponding to their amounts in real biomass was studied. It was found that the yield of biochar decreased with temperature in both of the processes, whereas the degree of deoxygenation, the amount of carbon in the biochar, and its calorific value increased. A comparison of biochars from biomass and model mixtures was carried out. An assumption on the screening effect of lignin in heat treatment, which reduced the degree of degradation of the structural components of biomasses, was made.
